“…Beyond that, thus far, the role of pre-service primary school teachers' interdisciplinary competence in teaching Sachunterricht has been addressed within educational research primarily from a theoretical perspective (e.g., Kalcsics, 2021;Künzli David et al, 2016;Wilhelm & Brühwiler, 2016). Although there is a growing body of research that empirically investigates university students' interdisciplinary competence, especially within higher education (e.g., Braßler & Dettmers, 2017;Engelhard 2019;Mansilla & Duraising, 2007) and engineering education (e.g., Richter & Paretti, 2009;Tormey & Laperrouza, 2023), to the best of our knowledge, such research has not yet been conducted with respect to the interdisciplinary competence of pre-service primary school teachers. In particular, there is a lack of empirical research, in Germany and internationally, about whether preservice primary school teachers' interdisciplinary competence changes over their university-based teacher education and to what extent interdisciplinary competence is correlated with the domain-specific orientations of pre-service primary school teachers (e.g., their interest, academic self-concept, and sense of belonging regarding natural and/or social sciences).…”
